Fig. 1G shows a detailed sectional view taken on the line 16, 16, of Fig. 3, looking in the direction of the arrows; and Fig. 17 shows a detail view of the bearing bars with ring attached.

Referring to the accompanying drawings I have used the reference numerals 10, 117 12 and 13 to indicate the diierent harrow sections used in my improved barrow. The sections 14, 15, 16 and 17 comprising the evener bar, are detachably connected by the hinges and the detachable pins 19. A cross bar 2O is connected tothe cvcner sections le, 15, 16 and 17 by the chains 21 and 21a. The motiv; power is applied to the evener bar through the ,ring 22 and the links ."ffl, which are eonnectoci to the cross bar 2C. es .shown in Fig. i'.

` tion being` hereinafter more rod in each section being pivotally connected to the operating lever 29. Bars or rods 37 are pivotally connected to the bearings 24, 25 and 26 holding them apart in their proper relative positions and at the same time allowing them to move vertically, except when in one position of their adjustment, said posifully described.

The upright levers 35 on the central teeth supporting bars in the sections 12 and 13 are provided. with upwardly extended projections 35, said projectionsbeing designed to engage the bars 33 in the sections 10 and 11, 'when sections 12 and 13 are in folded posi. tion (see Fig.,2) to obviate the strain on the hinge connections between the outer and inner sections, as hereinafter more fully described. i'

The connections 'for securing the harrow sections together when vnot in operation comprise two members. In the bearing connection members ywhichare applied to the. intermediate sect-ions 10 andll the numeral 38 indicates the bearing portions which fit over thevendsfof the forward and rear teeth supporting'members 23". `Runners't) ex-y tend downwardlyand rearwardly from said portions and are designed' to reeeire the weight of thel intermediate 10 and l1 when'vthe teeth 231 are moved to positions from engagement with the ground surface.

The extensmns'l on the bearing portions 38 are pro fided with cross bearings 4.1 and shoulders 4t2 for purposes hereinafter described. 1inwardly extended bearing bars 3S are fixed Ato bearii'ig portions .3S and are designed toseat inthe teeth supporting bars 23`to form wearing surfaces for some of the bearings.- to be fixed to ,theforwarll und rear supporting members 23 of the intermediate hai-row sections lO and ill by pins 38" extending through the 'openings 43 `'and 43 in the portions 3S, and bars 38a. The hook connection members are appliedto the inner ends of the front and rear supporting member-i523 in the end harrowsections l2 and t3, the bearing portions of which are indicated by the reference numerals 44. The extensions 45* on the connecting members tf1 are provided with hooks etti spacedapart from eachother and are also provided with lugs t? extending upwardly therefrom.' Outwardly extending bars e4" are fixed to the portions 4.4, said members being fixed to the supporting bars 23 by pins 449 extending through the openings 4t) and also lthe openings 42 in the bars 4LP. 'The bars 4,4,.like the bars 3S, above referred to, are adapted to seat in the members 23a to form wearing surfaces for the Abearings 24, 25 and Z--as shown in Figs. 4t and 5. T he connecting members are connected as shown in the Fig. 13 of the drawings, the hooks d6 engaging the bearing members 41 to prevent up ward movement of the hooked connection' members,

lugs when the turned to positionswith :the teeth 23b Y'mounted in the bearings ing between barrow sections Said members are designed the sholilders 42 engaging the hooks 46 and the lugs 4T engaging the outward extending portions 40 to `prevent further inward movementnof said hooked members to thus carry the end 7'0 hai-row sections 1n a `folded position as shown in Fig. 2 of the drawings.

The bearings 25 are providedwith iianges` 49h extending outwardly from each side, each being provided with tending flanges 50 and 51.' Pins 52 are mountedin said flanges 50-and. 51 to form bearings for the rods or bars 37. Lugs 53 extendlng outwardly from the vfaces of the bearings-25'arev designed to 28, saidpins being in engagement with fsald; supporting members 23?1 :are out of engagement with the ground surface.V 1 YVith this arrangement of parts' as described the supporting members 23" being Y and willbe free to -moveverti-v cally except when thepinsi28 engage --the lugsv 53, atfwliichftiine thevbearings -25 are stationary, the flanges 49h vthen preventing rertical movement. of the same, ing a substantially rigid barrow section.' The bearings 2st and 26 are similar to the bearings 25, except that only {lang-es 19,v` 50 and 5l therefrom. i The flanges wardly from the bearings 24 are provided with openings 55 to which the chainsfEZl-are attached.

'lo obtain suit-able bearing surfaces for the bearings 2st, 25 and 26, I have provided 105 and,

together with the bearing bars 45t the bars 25" extending inwardly from lthe rings 25 said rings being designed to tit on the ends of the teeth support-ing bars where said bars 25 fares for the bearings tions` where bars 238, it, and 25 'cannot be used, I' have .provided bars 29, designed to be seated i the teethsupporting bars andlo be fixed thereto the bearings and Yfor the rotatably mounted sector 31, as shown in Figs. 14 and 15.

To obtain a three section barrow, the section 10 "is used in connection with the see-1 tions 12 and 13 in the manner y scribed. The evener bar sections 15,` and 17 are connected to the said sections by the chains 21 as shown in Fig. 3. Power is then applied to said evener sections 'through the ring 58 which is connected to said sections 125 by ne Chains 5e and um inks-5t;

'in practical operation of my device, assuming that the* four barrow sections are in extended position and disconnected ,from

each other, the operating levers 29 are ad-- MOv downwardly ex- 5 .25 and said mgm i" the'tlanges 5-1 and 52, will befv vprevented from 'longitudinal movement .by 90 said iianges,

thusVA fornii one.` set vof Y. extends" outwardly 'l 54 extending out-,1go

Inposifor bearing surfaces for. 1125y above dein predifatermined relation, and a rigid :inseam uitisted relative to the sectors 3l elevating the teeth to substantially vertical positions. The narrow is then drawn overthe ground surface each teeth supporting bar being tree to ymove vertically thus accommodating itself to the nnevcnness of the ground vsnrace. Y{fili/'hen it is desired to pass tbrongli a gate or other narrow opening the levers 2.() are moved forwardly thus changing tbe liar- `row teeth to position away fromtlie ground surface and allowing the Weight of tbe ln termedialel barrow sections l0 and il to rest upon the runners 39 and also ,moving pins 28 to position in engagement with the lugs 53 on tbe bearings 24, 25 and 2li to form a rigid construction of each section. During the normal use the iront and rear bars are heid in. rigid relation to one an other by the connecting member which bridges the intermediate bars, While the intermediate bars are left somewhat free to float up and down in accordance with the inequa ities of tbe ground. But' when the hand/,Jever is rocked forward to take tbe teeth out. of engage-ment with tbe ground and toidrop the barrow sections on its four runners, the pins on the tooth bar engage the stops on they bearings and twist those bearings sntiiciently to tighten np all slack in the connections, yielding a connection wbicb which is snpat its four corners the four run- 'i`iie ioolied conneV ion members on re 'then applied to iec'tion members on Ytlne 1s rigid from end to end and ported ed upwardly and tilted d intermediate liarrovy position. The mener row section oids with i for eacli corresponding narrow section. enter sections are in folded-position,

tbe

proiectionsR35a of tbe upright levers rest on tbe bars l2-l ot the inner sections, yhereby relieving tbe hinged connections 38 and fifi oi' undue strain. To again obtain an operative device it. is only necessary to lower tire end barrow scc ns anddisconnect them from the intermediate sections and move tbe operating levers 29 rearwardly to bring the barrow teeth again in engagement with the ground' surface. Vi/*hen it desired to use three sections the intermediate section l0 is used connection with -tlne end sections l2 and 13 as above described, the evener section ii'- bcing discarded.
